Appcelerator titanium runtime error

Question

I have an existing project that was not developped for more than a half a year. Now i need to support it. I have updated Titanium SDK and all other libraries used in the project. But right after the launch of the application on the device i have runtime error. The screenshot of the error:

I'm surprised because this was the stable version of the app ready for production. So only after updating libraries this error occurs. Here's some parts of the code:

This is the 'index' view:

<?xml version="1.0"?>
<Alloy>
<Widget id="drawer" src="nl.fokkezb.drawer">
    <Window module="xp.ui" role="leftWindow" >
        ......
    </Window>
    <NavigationWindow platform="ios" role="centerWindow">
        <Require type="view" src="Home"/>
    </NavigationWindow>
    <Window module="xp.ui" platform="android" role="centerWindow" home="Home">
        <Require type="view" src="Home"/>
    </Window>
</Widget>
</Alloy>

and HOME.xml

<Alloy>
<Window id="winHome" platform="ios" class="container whiteBackground no-navbar" navBarHidden="true" layout="vertical" opacity="1">
    <Require type="view" src="homeContent"></Require>
</Window>
<Window id="winHome" platform="android" class="container whiteBackground no-navbar" navBarHidden="true" layout="vertical" opacity="1">
    <Require type="view" src="homeContent"></Require>
</Window>
</Alloy>

and homeContent:

<Alloy>
<View id="winHomeContent" class="container whiteBackground" layout="composite" visible = "false">
    <View class="ver">
        .........
    </View>
    <View bottom="0" class="h-size">
        <Require type="view" src="homeFooter"/>
    </View>
</View>
</Alloy>

I see that both 'index' and Home views have "Window" tags. But this exact code was working earlier.

Answer 1

In index.xml from Doc nl.fokkezb.drawer

centerWindow role is a View not an Window

<Alloy>
    <Widget id="drawer" src="nl.fokkezb.drawer">

        <Window module="xp.ui" role="leftWindow">
            <Label>I am left</Label>
        </Window>

        <NavigationWindow platform="ios" role="centerWindow">
            <Window>
                <LeftNavButton>
                    <Button onClick="toggle">Left</Button>
                </LeftNavButton>
                <Label>I am center</Label>
                <RightNavButton>
                    <Button onClick="toggle">Right</Button>
                </RightNavButton>
            </Window>
        </NavigationWindow>
        <View platform="android" role="centerWindow">
            <Label>I am center</Label>
        </View>

        <Window module="xp.ui" role="rightWindow">
            <Label>I am right</Label>
        </Window>

    </Widget>
</Alloy>
